Tristan obtained a Master's of Science and Engineering in Materials from France before moving to Seoul, South Korea to complete a graduate degree in Neuroscience / Psychology at Korea University. During his PhD, Tristan learned extracellular electrophysiology and optogenetic techniques as well as animal behavior. He then moved to New York City as a postdoctoral researcher in the laboratory of Attila Losonczy at Columbia University in 2017. During his postdoc, Tristan used multiphoton imaging to uncover the organization and function of hippocampal microcircuits responsible for our ability to learn and remember. A large portion of his research was also devoted to developing experimental methods that offered new vistas into the anatomical and physiological integration of individual neurons into large networks. Tristan joined the faculty of the Department of Neuroscience at Yale School of Medicine in 2024, and is a Wu Tsai Institute Investigator.
